To all whom t may concern:

Be it lmown that I, GEORGE D. LUCE, a citizen of the United States, anda resident of New Orleans, in the parish of Orleans and State oflLouisiana, have invented a new and Improved Core-Plate for Levees, ofwhich the following is fa full, clear,fand exact description.

This invention relates to means for dam-- ming or controlling 'the flowof water, and has particular Areference ito means of this characteradaptedfor reinforcing levees or the like, whereby it'is impossible forsuch embankments .to be damagedby the operations of musk rats or crawfish.

A further object of the invention is to provide a means forstrengthening ,levees already built and also to provide al means foradding to the height thereof in a simple, convenient and reliablemanner.

The foregoing and other objects of this invention will be hereinaftermore fully described and claimed and illustrated in the drawingsaccompanying this specication in which like characters of referenceindicate corresponding parte in all the views, and in whichv 4 Figure 1is a vertical transverse section of a levee fitted in accordance withthis invention; Fig.-2 is 'a fragmentary longitudinal section of a leveeshowing my improved construction in elevation; Fig. 3 is a transversesectional detail .on the line 3-3 of Fig. 2; and Figs. 4 and 5 aredetails hereinafter described.

Referring particularly to the drawings, the letter -L indicates asection of a levee adapted to prevent the overiiow from a body of waterR. In this levee is shown ametallic structure 10 shown in particular inthe remaining figures.

The metallic reinforcement above set forth comprises a series of panels11, each panel comprising a series of plates 12 arranged one aboveanother vertically. Each plate comprises a fiat web 13, a marginal rib14 on one side and a slotted head 15 on the opposite side. The rib 14 isprovided at one end with a projecting finger or stud 14 and at the.other end with a socket 14 adapted to receive the stud 141 of the nextadjoining plate. By this means all of the ribs 14 of each .panel aremaintained in substantial vertical alinement. AThe slottedhead 15 isadapted to receive the rib 14 of the next -adjoining panel when thestructure is in its completed form.

The manner ofl using this improved device is substantially as follows:Any 'desired numberof plates 12 are arranged one above another, as abovedescribed, in accordance with the height of the reinforcement desired.With the plates arranged in substantially the same plane, a rigid bar 1Gis inserted into the alined heads l5 of said panel.c The panel thusarranged is then driven intoA place, as, for instance, by the use of apile driver. The plates being comparatively thin, and the soil at suchplaces being of a comparatively soft nature, the panels may thus bereadily driven. After .a panel is driven, the bar 16 is withdrawn fromthe heads 15 and a second panel is prepared and arranged with the ribs11i thereof inserted into the upper end of the uppermost head 15 of thelast panel. The

bar 1G then being inserted in the heads of the second panel, said secondpanel will be driven as before. it is preferable, as indicated in Fig.2, for the several plates of the r respective panels to be arranged withbroken joints, as indicated at 17. If desired, the meeting edges ofadjacent sections and adjacent panels may be filled with cement or othermaterial for the purpose of rendering the reinforcement waterproof. As aconvenient manner for thus` uniting adjacent panels, the hole formed bythe alined heads 15 of the .panel last driven may be filled with a soft,thin cement, Iwhereby, when the next panel is drivenA intoplace, themeeting surfaces of the panels will be subjected to the action of thecement.

The plates may be made of any suitable material, preferably metal, andmay be made of any suitable size or weight, depending upon the characterof the service to be performed thereby.

Having thus described my invention, I claim as new and desire to secureby Letters levees comprising a plurality of panels, each u I pimacompm'g a series 0f verical plates armmgdf. one above ancnher, each pmteharvng allang; on@ edge a head and along thev opposi @ge n, rib, theribs.` of on@ panel' tang into the heads of the maxi; pand, and each fahaving a, lug and also having a sofsket adapted, receive the lug of thenext adjmemf pafe, Suostmntialy as set forth.
